Is this video card compatible with my motherboard?

I have a " PCI Express x16 (running at x 4)" slot. The video card in question requires "PCI Express 2.0". I don't want to buy something I won't be able to use so thanks for your help.|||Yes, it is compatible. A PCI Express x16 slot fits 2.0 cards and 2.1 cards (they're basically the same thing)|||PCI Express 2.0 Cards are backward compatible with old standard PCI-Express X16 cards, so it will work just fine, it just will not run as fast as it could.
